Executing Turbomole from chemshell

[yasser-qm]

Hi

I'm trying to run a QMMM optimization using chemshell with TURBOMOLE for qm region.

My qm region has 169 atoms

My jobs are crashing during the dscf step because of insufficient maximum number of 2e integrals and suggest to increase the maxtask in control.

Questions:

Does any one know how to fix the maxtask from the chemshell script, without re-using the control file?

Thanks!

Hi,

this looks like an old version of Turbomole (6.4 or older I guess). The task distribution is done by dscf automatically during runtime meanwhile, there is no need to set the $parallel_parameters keyword any more.

Regards,
